Actionscript 3 :: Several Second Computation In A Game While Maintaining 60 FPS
Jul 12, 2010
I've got an algorithm that takes more than several seconds to complete. I'm trying to implement it into a 60fps flash game i'm creating. I am wondering if there is some provision in ActionScript3 to interrupt a computation in order to update the frame and continue the computation afterwards. There probably isn't, so I'm assuming the best method would be to perform the computation for x milliseconds, measure what the frame rate is after, then adjust the time the computation will run for next frame if the frame rate is less than or greater than 60 fps. The drawback with this is that the game won't run at a steady 60fps...
Any other ideas on how to (optimally) perform a large computation in AS3 while maintaining the framerate? EDIT: For the curious (the calculation, perhaps I should have said algorithm): I'm creating a motion planning library for game AI objects (one use for motion planning). The algorithm is along the lines of a RRT (rapidly exploring random tree) that iterates thousands of times. Demo link:[URL] Click to motion plan. The circle can "thrust" at a fixed magnitude in any direction. Also - there is no linear velocity damping (i.e. friction).

Is it possible to define the scenes and the frames in XML in Flash CS4, so that we can parse it in actionscript 3.0 and define the interactivity. I want to define all the UI elements and the event associated with UI like List control or button in XML format (XUL??) and then use actionscript to build the application logic. Are there some good examples?

I am creating a site in flash, and I have always had this problem when I make flash sites. How can I eliminate a scroll bar in the browser, and make the swf fill the entire browser window no matter what? Is it something I need to write in Actionscript? the HTML page?

I using FlashMX to read in a value from an ASP page into a dynamic text box. This works fine.
I then use a motion tween animation to tween into another image, and there I put another instance of the dynamic text box, with the same name, but the value doesn't populate the text box. It's as if it reads the variable into the text box, but if I do anything to the text box, it loses the variable and can't get it back.
Further, if I switch back to the first frame, the value won't populate either, I have to refresh the browser page to repopulate the variable (read the ASP page again.)
Is there a way to maintain this variable throughout the movie, so that I can re-use it?

I am working on a paint application, I am able to draw lines, draw shapes, erase. I need to implement undo and redo functionality. I plan to store history in a bitmap and put it in an arrayMy question is whether we can have an alternate solution other using bitmap class. How can I store coordinates of non straight line without using up lot of memory and processor.

I have a project which, for all intents and purposes, attempts to create an online text editor/word processor. The key thing is that I need all multi line formatting to be retained and sent to the server. ie, if the user enters a bunch of text (all colors/bold/fonts and stuff are working great) which has a carriage return or a line wrap, I need a way of tracking that and inserting some kind of flag to let the server now to break to the next line at that point.this project is a client/server application so just storing the text string and expecting flash to be able to use the same size text box will not work.
I have created a function that detects keypresses and MOSTLY takes care of the carraige return issue (still not as solid as I'd like though). Basically, every time the user presses return, I store the length of the string and, when parsing the data for transfer, I insert newline chars at every index point where one is needed. This mostly works unless the user goes BACK and enters a return (still working on that little issue).But the word wrap part is killing me. I did find several discussions of using either total characters to determine how big the box is and where to break the line, or something along those lines, but here's the main issue with that:everything is dynamic. the user can change almost everything, from text font (so there will be variable font widths) text size (again, variable widths) to textbox size (so I can't go with a fixed pixel size to break the text). I've noticed that it was very easy to make a text box vertically dynamic, but the width seems to want to stay fixed (if set to multi-line) since the user will be changing this width, I'm just stuck.
if it means coding a huge set of functions that compares every possible font (i will be using embedded fonts eventually so they will be limited) with every possible size and then using that data to determine box size, that's fine, I'll do whatever I can to get this working, but there just has to be an easier way

I have recently purchased Pageflip 3.6 (http://pageflip.hu/) for a project at work and what I am planning on doing is implementing a guest book which i have created in flash.The guest book I created consists of a file upload (for images) a comment entry and a signature section (where the user has a choice between a bunch of fonts and writes there name) which are located on the left page of the flip book and then on the right page it displays the post (using XML).
Now the guest book on its own works like a charm, but when it is called into Pageflip the buttons for the upload/submit stop working and nothing happens.The way Pageflip pulls in the swf/png/jpg to fill its content is through an XML file.Pageflip does have hot spots and controls to switch pages directly within the book but I have disabled them so that you can only switch pages through the control bar, as I thought the hot spots were conflicting with the input for the guest book but it didn't do anything it still will not allow me to use the controls for the guest book.
I know this might be kind of confusing I hope i described my problem clearly enough and any help or input at all would be fantastic. I'm fairly green with actionscript but i'm the only one at my agency that knows how to use it so its tough on me to do these advanced things without anyone to bounce ideas off of

I'm having a conundrum. I am trying to duplicate the link effect: http:[url]....The thing about that is that I am trying to create this for an HTML site as link transitions for a client. My issue is that the swf has to maintain size on ALL browsers and sizes. I've tried setting the html object sizes to 100%, but the video is smaller. Is there something I'm doing wrong?

I am going to be utilizing a flash/jquery powered gallery on a webpage that is maintained and updated with an xml document. The xml data is used to add and sort images into a grid of small thumbnail images. i will customize this component so that when the user rolls over a thumbnail it will trigger jquery to replace a div using hide/show. My employer would like to try to create an adobe air desktop widget that will mirror the content of this gallery so that as entries are added to the site users can access the content automatically via the desktop. I was thinking there may be a way to utilize the same xml document to maintain the app as well as the gallery. As there is a fairly tight turn around on this project, i was wondering if anyone could confirm that adobe air apps can be maintained in this way, or how to approach this particular client request.

I have a canvas component called myCanvas and I instantiated it with
var myCanvasPage:myCanvas = new myCanvas;
this.addChild(myCanvasPage);
Then I want to essentially reload myCanvasPage later on. In effect I want to do this:
this.removeChild(myCanvasPage);
var myCanvasPage:myCanvas = new myCanvas;
this.addChild(myCanvasPage);
except instead of creating a new instance of myCanvas, I want to use the already created instance of myCanvas and essentially reload or re-create it but making sure that the instance name and references to it remain the same.

I have a TLF editable field in a(n) swf file. Text entered there gets sent to a php page where everything is processed. I had the behavior set for multiline, but just realized that if someone hits return and keeps typing, no break is displayed (not even a space). I've tried using nl2br() in the php when it grabs the POST variable from flash, but that doesn't work. I don't know how flash handles the carriage return, so I don't know how to handle it on the php side either.

I pretty much got it working. The only problem I'm having is that it's only full screen based off of the width. I want the picture to maintain it's scale, so I need it to fill the height if necessary and cut the sides off of the picture. You can see what I mean by clicking [URl]. Resize the browser so it's a lot taller than it is wide and you'll see what I mean. I want it to fit both height and width no matter which is taller. I've played around with it all morning and nothing.
Code:
// pic_mc is the movieclip that I used to load my full-screen background image.
function bgResize() {
pic_mc._width = Stage.width;
pic_mc._yscale = pic_mc._xscale;
if (pic_mc.height >= _yscale) {
pic_mc._x = (Stage.width)/2;
pic_mc._y = (Stage.height)/2;

I'm trying to highlight the current 'page' / movieclip by showing the onrollover state in navigation display/button.So the colour remains the onrollover state (in this case blue) while the particular movie clip/'page' is displaying. Changing when the user rolls over another button.I have two issues:1. I understand I have to place the button within a movieclip and have been experimenting with button '02' in the attached example.fla - however now I have done this the original action contained within the movieclip instance myScreen_mc is no longer working.

I have a flash app which will send/receive a constant stream of data. The flash app should open a connection to the Java server, keep it open, and attempt to reconnect on socket failure. Are there any good APIs that offer this functionality? Smartfox Server is one option, but if I had my way I'd embed an API in my app rather than contort my app to run under Smartfox. Ideally it would offer an API on the flash end, another on the Java end, and efficiently (java nio preferably) handle the network component in between. I would just define handlers on both the client & server.

I'm trying to shape tween a movie clip of a rocket blasting off. I want it to "squash" before liftoff, and then "stretch" as it lifts off. When I tween this on the timeline with the transform tool, I can "squash" the rocket, and the base of the rocket stays on the "ground". This is what I want. However, for reasons I won't go into, I need to do this in AS3, as opposed to on the timeline. When I use a "height" tween, though, the movieclip height changes, but it shrinks/stretches at the bottom (locked at the top). Is it possible to do what I want with the tween class? Do I need to use something besides "height"?

Notice if you adjust your browser size in both direction, it'll resize itself accordingly.
But if you resize in only one direction (squish your browser left) it won't resize at all past its aspect ratio..
Same if you squish your browser upward (with out resizing to the left or right), it'll resize till the aspect ratio is good, but if you continue squishing your browser up, it'll simply stop resizing all togethor and crop it.. AS well as the top portion of the flash file never moves up.
I want to make a full flash page, but allow the aspect ratio to be maintained when people adjust their browsers, so it can be resized if the browser is at a smaller resolution, but if they only move one side of their browser, nothing happens, (try it on the jimcarrey site to see what I mean, if you size your browser in both directions, the site resizes, but if you resize your browser in only one direction, say like up/down, it'll just crop out the bottom once the aspect ratio is met.

I need to find a way to copy a masked bitmap. I have a bitmap on stage, and a user drawn sprite that acts as a mask. I need to capture/copy the masked area bitmap, maintaining the transparency created by the masking to eventually encode as a png.
I could find no documentation on how to accomplish this using copyPixels(), or any other directions.

I'm using Flash CS4. Everything functions as it should when CS4 previews the swf after compiling it. However, after embedding the flash item in a webpage, if the textArea loses focus within the flash piece, the textarea's built-in UIscrollbar resets to the very top. Here's the kicker: if I add a FOCUS_OUT event listener to the textArea to store the current scrollbar value, I find that the scrollbar value has been reset to minimum even before the FOCUS_OUT event is triggered! WTF? I think this is occurring because the textArea's htmlText propery is dynamically populated. Adobe AIR has advanced methods for handing HTML, but not simple AS3, oh no. How obnoxious. What can be done?

i posted this on actionscript.org with a reply, but the code provided by one of the admin only did half the trick. maybe further assistance can be provided here. so i have a set of buttons arranged in a sort of gallery menu, such that each button is a link to a different set of pictures. the menu stays visible the whole time, while the corresponding pictures are loaded into an empty movie clip. what i want to do is have these buttons, when pressed, show their down state (to indicate which item the user is currently viewing), until a different button is chosen. in which case the new button will then show its "down" state and the former button will return to its "up" state.
so just to clarify. say i have buttons "1" , "2" , "3" , "4". the user clicks number "3". the button turns from red to blue, loads the appropriate content and remains blue until, say button "4" is pressed. button "3" now goes back to red, and button "4" becomes blue and loads the content.
